DHCP Server on HPE Aruba ArubaOS-Switch

HPE Aruba ArubaOS-Switch has a built-in DHCP server. This guide covers creating a DHCP pool, enabling it on a VLAN, and adding static reservations for individual devices.

Important: You must disable the DHCP server globally before making any changes to pool configuration.

Create a DHCP pool #

cli

conf t
dhcp-server disable

dhcp-server pool "GUEST-DHCP"
   authoritative
   default-router "192.168.0.1"
   dns-server "8.8.8.8,8.8.4.4"
   domain-name "test.local"
   lease 00:01:00
   network 192.168.0.0 255.255.254.0
   range 192.168.0.21 192.168.1.149
exit

Enable DHCP on the VLAN interface #

cli

vlan 10
   name "Guest Wireless"
   ip address 192.168.0.1 255.255.254.0
   dhcp-server
 exit

conf t
dhcp-server enable

Static DHCP reservations #

Each reservation requires its own named pool. Disable the server first:

cli

conf t
dhcp-server disable

dhcp-server pool "Printer-1"
lease infinite
static-bind ip 192.168.1.250 255.255.254.0 mac 001234-5678ab
exit

dhcp-server pool "Printer-2"
lease infinite
static-bind ip 192.168.1.251 255.255.254.0 mac 001234-5678ac
exit

dhcp-server pool "Printer-3"
lease infinite
static-bind ip 192.168.1.252 255.255.254.0 mac 001234-5678ad
exit

conf t
dhcp-server enable

Static reservation IPs must fall within the range defined in the main pool.
